[Spoilers] Heldalf battle, surviving the big attack

[john.r.moser]

Heldalf keeps using a one-hit KO attack and I haven't managed to beat him yet. He takes a lot of damage to knock down and I can't use mystic artes.

So far, I've managed to get past the first one twice, although I only managed to fire the gun at him once. I didn't survive the second attack either time, even though I had four live Seriphs while he was below half health once.

Is there a trick to this, or do you just beat him down and try not to die?

When he is charging the attack, you need to keep attacking until his HP reached a certain and he will automatically be stunned and you will get the option to fire the gun. However, the amount of damage to to reduce his HP required increases after each gun strike.

During the charge, try to use Blast attacks because they deal High amount of damage. And also try to use rates that he is weak against. There is another "weakness" mechanic in this game called "type-weakness". Since the armatize is partly a dragon type (can check his monster by holding 'target' button during battle), it means any Arte that has the dragon symbol in the description menu will be more effective.
